IMPROVEMENT IN EVELEllNG-MACHINES.

Specication forming part of Letters Patent No. 158,343, dated December 29, 1874; application tiled July 24, 1874.

To all whom t may concern.-

Be it known that I, JOHN E. WreerN, of Stoneham, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Eyeleting- Machines, of which the following is a specification:

The nature of my invention consists, first, in an improved device for presenting the eyelets to the delivery device. The deliverychamber of the machines can be supplied direct from the mercantile package of eyelets. Second, in an improved carrying or delivery` ing device, by which each eyelet is taken on a stud and moved with precision to the pistonfeeder. Third, in the piston-feeder, which is a vibrating sliding bifurcated lever, which seizes each individual eyelet (as it is presented from one of the studs of the delivery device) and passes it onto the piston-anvil. Fourth, in an improved device for holding the eyelet onto the piston-anvil while it is being placed in the eyelet-hole.

Figure l is a side elevation of my invention. Fig. 2 is a horizontal section ofthe same. Fig. 3 is also a side elevation, taken from a point of view opposite from that which Fig. l is taken.` Fig. 4 is a horizontal section, taken from a lower plane than the section of Fig. 2, and vis intended to show the operatinglevers. Fig. 5 is an elevation showing'the eyelet-piston and its adjuncts. Fig. 6 is a vertical section of the eyelet-piston and its adj uncts. Fig. 7 is a perspective view of a part of lthe eyeletpresenting ring. Fig. 8 is an elevation of a part of the eyelet-presenting ring. Fig. 9 is a horizontal section taken on line .r y of Fig. 8, showing also a part of the eyelet-deliverin g device.

Let A represent the base ofthe machine, to which the other parts are attached. H3, Figs. l, 3, and 4, is a vertical plate of metal, surmounted by a fixed circular disk, H, Figs. l, 2, and 3, and by a triangular plate, H4, Fig. 2, the edge of which is indicated by H1, Figs. 1 and 3. C, Figg, represents a basin or cham ber sunk in the disk H. The bottom of this basin or'chamber C is convex-that is, highest in the center. G C' C C', Fig. 2, are xed elastic arms, curved as shown. E, Figs. l, 2, 3, 7, and S, is a ring of metal, placed in the chamber C, as shown in Fig. 2. The outer circumference of this ring E has ratchet-teeth cut into it. M, Figs. l and 2, is a pawl, actuated by the lever-N. By giving motion to the lever N, as will be hereafter explained, an intermittent motion is imparted to the ring E. F, Figs. l and 3, is a stationary cap, which tits over the basin C, and forms the eyeletchamber. This eyelet-chamber has a tube, G, Figs. l and 3,wl1ich is to be connected by any suitable pipe with the mercantile package of eyelets, so that the supply to the eyelet-chamber may be constant.

The action of this part of the device may be explained as follows: The chamber G being filled with eyelets, and the machine being started, the ring E, Fig. 2,wit-h its dentals el c1 e161, Figs. 7, 8, and 9, moves iu the direction of the arrow, Figs. 2 and 9. This action, in connection with the stationary arms U O C G, has a tendency to force the eyelets into the spaces c2 e2 e2 e5, &c., between the dentals el el e1 c1, Sac.; and as the spaces are so shaped that the eyelet cannot enter them unless the eyelet stands flange down, it is evident that as the ring continues to revolve, each of the spaces e2 c2 c2 c2 will soon be tilled with eyelets, and as the spaces e5 c2 e2 e2, Ste., arev inclined, as shown in Fig. 9, all of the eyelets have a tendency to work outward; but they are held in position by the ring H, Figs. 2 and 9, until they reach the point L1, Figs. 2 and 9, where the ring H is out, and where the carrier K, with its studs k 701 7a2, &c., is located. The carrying device consists ot' a ilat plate, K, Figs. l and 9, having studs 7c k1, Ste., projecting upward from it. The carrier K is located `as shown in Figs. l, 3, and 9. The plate K,

Fig. l, is connected to the sliding plate L 5, Fig. l, by means of links K1 K2. This sliding plate N5 is operated by the lever N, which acts through the link NS and stud N4', Fig. 4, the stud N 4 being connected with the sliding plate N5. K5, Fig. l, is a buttress, which prevents the link Kl from swinging beyond the position shown in Fig. l, so that when the plate N5 is thrown in the direction of the arrow S, the carrier-plate K will have to move with it; but when the plate N5 is moved backward, the frictionlink K3, governed by the friction-screw K4, will resist the backward motion of the carrier K. The resistance thus offered will cause the links K1 K2 to swing downward. This causes the carrier K to drop so as to withdraw the studs 7a k1 k2, 'cc., below the-face ofthe plate H1, Fig. 1in other words, to draw them out of contact with the eyelets. The continued backward motion of the plate N5 will swing the links K1 K2 so as to bring the carrier-plate K to its lowest limitsthat is, so it will come in contact with the top of the buttress K5. Then the carrier K will have to move backward with the sliding plate N. (See Fig. l.) The dropping and backward motion of the carrier-plateK is so limited that the first stud, k, will be immediately under the eyelet-delivery point L1, Figs. l, 2, and 9, of the ring E. Now, the next movement of the machine will cause the sliding plate N5 to move forward, the first action of which is to cause the links K1 K2 to swing toward a perpendicular line, since their upper ends are held by the friction-link K3. This throws the carrier-plate K directly upward, and causes the first stud, 7c, Fig. 9, to enter the eyelet T, which is at lthe delivery-point L1 of the ring E. Now, the continued forward motion of the plate N5 will move the carrier K forward, because the link K1 is stopped by the buttress K5 from swinging farther toward the perpendicular. Thus one eyelet will be carried forward 011 the plate H1.

Let the above series ot' motions be repeated, and the eyelet on the first stud, 7c, will be left on the plate H1 at a distance from the delivery-point L1 equal to the forward motion of the carrier K. This distance is also equivalent to the space between the studs 7c k1 k2, 81e., so that the next time the studs k k1 k2, &c., come up the stud k will take a new eyelet from the delivery-point L1, and the stud 701 will take the eyelet already passed out and forward it one space. A continued operation of the machine will take out a new eyelet at each motion, and forward the others already acted upon 011e space toward the end K8 ofthe piston-feeder K7 K8.

L, Figs. l, 2, and 3, is a flat plate immediately over the studs 7a k1 k2. This plate L is provided with a number ot' light fiat springs, m m m, Sac. These springs rest upon the eyelets, and thus keep them in place while the studs lc k1 7a2, &c., are not in connection with them. K"I K11, Figs. l, 2, and 3, is the piston feeding-lever, and is pivoted on a sliding pivot, K11, Figs. l and 3. This pivot slides in a housing, H1. The end K7 of the lever is pivoted to a standard, K10, which is attached to the sliding plate K, so that, at each motion of the plate K, the levers K7 K11 will move back and fort-h, and also swing in a vertical plane-that is, as the plate K falls and retreats the end K11 of the lever will rise and retreat, and, upon the rising and forward motion ofthe plate K, the end K8 of the lever vwill fall and advance. These parts are so adjusted that, when the end K11 of the lever falls, it will grasp one of the eyelets that has been forwarded by the studs 7a k1 k2, &c., and hold it in its fork-shaped mouth, as shown at K8, Fig. 2; then, its next motion being forward, the eyelet will be passed onto lthe piston or lower set P4, Figs. 1, 2, 3, 5, and 6. The piston or lower set P4, Figs. 5 and 6, slides in a stationary tube, P, Figs. l, 3, 5, and 6. The top of this piston or set has a central opening, as shown at P4, Fig. 6, to receive the point of the upper set, and is concaved slightly, so as to offer abetter seat for theeyelet. Pt and lt, Figs. l and 5, are fiat springs attached to a sleeve, P2. This sleeve is held up by a spring, P3, and is limited in its motion on the piston P4 by the slot and pin P5, Figs. 5 and 6.

When the sleeve P2 is thrown upward to its highest point, as shown in Fig. 5, then the upper ends of the springs R lie over the top of the piston P4, a-nd grasp the eyelet T', as shown in Fig. 5. When the piston P4 is thrown up to its highest point-that is, so it shall be on a level with the table S2, Figs. l, 2, and 3- then the upper end of the sleeve P2 will have come in contact with the stationary part H1, as seen in Fig. 6, and will have been prevented from rising a distance equal to the distance P4 rises; and, as the springs It R are attached to the sleeve P2, it is evident that the upper end of P4 will pass up beyond the top of the springs It R, these springs being so formed that the top ofthe piston P4 can pass between them, causing them to open and allow it (the top ofthe piston) to pass above the top of the springs R R. This action will release the eyelet and leave it in the eyelet-hole of the boot or shoe.

The lnotion of the piston or set P1 is regulated to correspond to the motion of the eyelet-feedin g mechanism, so that an eyelet is taken onto the set at each motion. In case the eyelet is not left in the eyelet-hole of the article, and is carried down on the set, it will be pushed off at the next motion of the lever K11, and will be thus prevented from interfering with the action of the machine.

The vertical motion is given to the piston or lower set P4 by the lever N2, Fig. 3, which, acting through the cam N7, gives motion to the lever O, the lever O being pivoted at O1, and connected to the piston by the pin O2, Figs. 3 and 5. While the eyelet is at the point of delivery, L1, Fig. 2, awaiting the action of the carrier K, it is held steadily in-its place by the spring L2, Fig. 2.

The mouth K8 of the lever K1, Fig. 2, is provided with a small spring, K6, Figs. l and 2, which serves to steady the eyelet while being operated upon by the lever K1. S1, Fig. l, is a stud projecting downward from the table S2, and serves as a guide for locating the eyeletholes in the different halves of the work, so they may correspond with each other.
